5.5. EUT Configuration on Test 
The configurations of EUT are listed in Section 3.5. 
5.6. Operating Condition of EUT 
5.6.1. Setup the EUT and simulators as shown in Section 5.2. 
5.6.2. Turn on the power of all equipments. 
5.6.3. Let the EUT work in test modes (BD Live / FM 88MHz/ FM 98MHz/ FM 108MHz) 
and test it. 
5.7. Test Procedure 
The EUT was placed on a non-metallic table, 80 cm above the ground plane inside a 
semi-anechoic chamber. An antenna was located 3m from the EUT on an adjustable mast. 
A pre-scan was first performed in order to find prominent radiated emissions. For final 
emissions measurements at each frequency of interest, the EUT were rotated and the 
antenna height was varied between 1m and 4m in order to maximize the emission. 
Measurements in both horizontal and vertical polarities were made and the data was 
recorded. In order to find the maximum emission, the relative positions of equipments and 
all the interface cables were changed according to EN55013 and EN 55022 Class B on 
Radiated Disturbance test. 
 
The bandwidth setting on the test receiver (R&S TEST RECEIVER ESVS10) is 120 kHz. 
The resolution bandwidth of the Agilent Spectrum Analyzer E4407B was set at 1MHz. (For 
above 1GHz) 
The frequency range from 30MHz to 1000MHz was pre-scanned with a peak detector and 
all final readings of measurement from Test Receiver are Quasi-Peak values. 
 
The frequency range from 1GHz to 6GHz was checked and all final readings of 
measurement were with Peak and Average detector, measurement distance was 3m at 
semi-anechoic chamber. The portion of the test volume that was obstructed by absorber 
placed on the floor (30cm maximum). 
 
Finally, selected operating situations at Anechoic Chamber measurement, all the test results 
are listed in section 5.8.
